Actually, the tattoos on the wall should but as it turns out they do not hold. We have the woodchip was died riche with latex paint. On Latex underground the tattoos adhere virtually not at all. To make matters worse, that the adhesive film is quite stiff and thus not at all to adjust little to the ground. We have already used the tattoos hold on latex surface and woodchip and their film is much more flexible. At the window I would glue the Tattoos on any case. The sun will ensure that the adhesive is to the windowpane to form a unit. Have fun scraping ;-) We would not buy the tattoos again.
